SB Payment Service is a payment processing platform from SB Payment Service Corporation, part of the SoftBank Group. It lets businesses accept payments through credit cards, mobile wallets, carrier billing, and over 40 payment methods with a single integration.

The platform serves a large merchant base across Japan and offers close integration with PayPay and supports all three major Japanese carriers (SoftBank, docomo, and au), making it well-suited for businesses targeting mobile payment users and requiring carrier billing options.

The service supports 3D Secure 2.0 authentication to add identity verification during card transactions, helping reduce chargebacks and meet card issuer security standards.

Merchants can accept payments from QR code-based mobile wallets including PayPay, au PAY, d-payment, LINE Pay, and Merpay through the platform’s payment gateway.

Developers can integrate payment processing using a REST API, enabling custom payment flows, subscription management, and programmatic access to transaction data.
